Read the guide →How building an app with Greta.sh works
Every app type above starts the same way: you describe what you want in plain English, and Greta.sh generates a working application — frontend, backend, database and authentication — that you can open, use, change and deploy. There is no template to fill in and no code to write, but what comes out is a real application rather than a mockup of one.
Describe the app, not the interface
The most common mistake is describing what the screens should look like. Describe what the app does instead: who uses it, what they need to record, what happens after they submit. "A CRM where sales reps log calls against a company, and a manager sees this week's calls by rep" produces a far better first build than "a dashboard with a sidebar and a table", because it tells the builder what the data is and who it belongs to.
You get a full stack, not a front end
Each build includes a database with real tables and relationships, a backend with working create/read/update/delete operations, user accounts and login, and role-based permissions where the app needs them. This is the line where AI-built apps usually stop — a convincing interface with nothing behind it — and it is the difference between a demo you can show and a tool a team can actually use on Monday.
Change it by describing the change
The first build is a starting point. Adding a field, changing who can see what, adding an export, wiring in an email notification — all of it is another sentence rather than a ticket. You can also connect the app to the services it needs: Slack, email providers, GitHub, AI models and deployment platforms are available without API keys to wrangle or glue code to maintain.
Pick the closest starting point
The app types above are starting points, not fixed products. If you are building something that is not on the list, pick whichever is structurally closest — a booking tool is close to a marketplace, an applicant tracker is close to a CRM — and describe your version. What matters is the shape of the data, not the label on the card.
Common questions
Do I need to know how to code?
No. The whole flow is written in plain English, and the app is generated, hosted and deployed for you. Developers can read and edit the generated code if they want to, but nothing requires it.
How long does a first working version take?
A first working version of a straightforward internal tool is usually minutes rather than days. What takes longer is the second half — permissions, edge cases, real data, the details specific to how your team works — which is the same in any tool.
Can I use my own domain?
Yes. Apps deploy to a Greta.sh URL by default and can be pointed at a custom domain.
What happens to the app if I stop using Greta.sh?
The generated code is real code and can be exported. An app built here is not locked to a proprietary runtime that only works while a subscription is active.
Build Something Real
If you can describe it, you can build it.
